REPEATING EXPLOSIVE MECHANISM.

Application filed November 14, 1907.

To all whom it may concern:

Be it known that we, HENRY A. BIERLEY and WILLIAM F. PROBST, of Portsmouth and Chillicothe, respectively, counties of Scioto and Ross, respectively, and State of Ohio, have invented a certain new and useful Reeating Explosive Mechanism; and we do ereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to provide a new and improved repeating explosive mechanism, one particularly adapted for feeding a tape supplied with a series of caps or explosives and for exploding said caps or explosives as said tape is intermittently fed through the device.

While we here show our invention embodied in what is generally called an explosive cane, we do not wish it to be limited to use in connection with canes or any other particular mechanism or construction, as it is adapted for use in a variety of forms only one of which, however, is herein shown for the purpose of illustrating the nature of the invention.

The nature of this invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a side elevation of the mechanism with the cane centrally broken away. Fig. 2 is a central vertical section of the exploding mechanism in its un o erated position. Fig. 3 is the same with t e parts in their actuated positions. Fig. 4 is a side elevation of the exploding mechanism with the ta e-holder in position for filling it with tape. Fig. 5 is a plan view of a portion of the explosive tape.

In detail the drawings herein show a cane 10 or other reciprocatory means with which the exploding mechanism below is secured. The device is operated when connected with a cane by moving the cane downwardly upon the sidewalk or the like with a blow. The cane is secured to the up er end 11 of a tapeholder 12 that is securec within a casing 13. The casing is open at the top and on one edge, and the tape holder is pivoted in the casing by a pivot 14 near-one lower corner so that the tape-holder can be swung laterally at the top partially out of the casing, as shown in Fig. 4, so as to expose the hole 15 in the tapeholder in which a coil of ta e 16 may be inserted with the free end thereof projecting Specification of Letters Patent.

through the slot 17 and down over the flat edge of the tape-holder that has in it a longitudinal groove 18. The tape-holder is held in lace in the casing by a removable pin 19. This ex losive tape contains a series of caps and exp osives 20 equidistant apart and holes 21 between them likewise equidistant from each other. The tape passes downwardly between one edge of the tape holder and one edge of the casing, as shown in Fig. 2, said edge of the casing being longitudinally slotted at 22 for the operation of the feed trip 23. This feed trip is fulcrumed between its ends in a bracket 24 that fits loosely astride the casing so as to be vertically movable thereon, and the trip has teeth 25 on its inner end that enter one of the holes 21 in the explosive tape when the trip is in its upper position, and feeds said ta e downward y as the trip moves downwardly. The teeth 25 on the feed trip are held in engagement with the tape by the outer end of the feed trip being weighted somewhat. The teeth on the trip project into the groove 18 in the ta e holder to enable the teeth to get a good 110 d on the tape for moving it. Such movement of the tape is retarded by the springs 26.

The free end of the explosive tape as it moves downwardly by the means above mentioned is deflected inwardly by the curved guide 27 horizontally under the lower end of the tape-holder 12, which lower end forms an abutment against which the cap or explosive is hammered and exploded by the hammer 30 that is vertically reciprocable in a pair of oppositely located downwardly extending guide plates 81 from the sides of the casing 13. These guide plates are slotted and in said slots a bar 32 on each side reciprocates, said bar being secured to the hammer and being normally drawn downwardly by springs 33. Said bars carry on their upper ends the bracket 24 in which the feed trip is mounted, and at their upper ends are guided by the guide lugs 34 on the side of the casing 13. i

From the foregoing description it is believed the operation will be understood. Assuming the tape to have been fed in between the hammer and the abutment on the lower end of the tape-holder 12 and the cane to be hammered down upon the sidewalk, the hammer will be moved to the position shown in Fig. 3 and cause an explosion. At the same time the feed trip 23 will be elevated so that its teeth will enter a new hole 21 in the tape. When the cane is lifted off of the sidewalk, the springs 33 will draw the hammer downwardly and at the same time the feed trip moves downwardly and feeds the explosive tape one more step. Since the holes and explosives in said tape are equidistant from each other, at every feeding movement a new explosive will be moved into position for explosion.

What we claim as our invention and desire to secure by Letters Patent is:

l. A repeating explosive mechanism including means for holding and guiding a tape with explosives therein to the exploding position, means operated by the operator for giving the hammer the percussion stroke, a trip for engaging the tape and feeding it forward, and a spring for returning the hammer and giving the trlp its feeding movement.

2. A repeating explosive mechanism including means for holding and guiding a tape with explosives therein to the exploding position, a hammer for exploding the same, a 'trip for engaging said tape and feeding it,

means on which said trip is mounted thatis controlled by the movements of said hammer and a spring for moving the hammer and causing the feeding movement ofthe trip.

3. A repeating explosive mechanism 1ncluding means for holding and guiding a tape with explosives therein to the exploding position, a hammer for exploding the same, a

-.trip pivoted between its ends for engaging said tape and feeding it, and means rigidly secured to said hammer for mounting and moving said trip.

4. A repeating explosive mechanism ineluding means for holding and guiding a tape with explosives therein to an exploding position, a movable hammer for exploding the same, a trip for engaging said tape and feeding it, means rigidly secured to said hammer for mounting and moving said trip, and a spring for returning the hammer from its exploding position, whereby said trip will be given its feeding movement by the action of said spring.

5. A repeating explosive mechanism including means for holding and guiding a tape with explosivestherein to an exploding position, a frame movable over said tape, a trip pivoted in said frame between its ends, one end thereof formed to engage and move said tape and the other end Weighted, whereby as the trip moves downwardly, itwill feed the tape, and as it moves upwardly, it will get a new hold on the tape.

6.: A cane, a holder for tape having explosives therein secured to the lower end of the cane, a casing surrounding said tape-holder provided with a guideway for passing the tape transversely under said tape holder, a

hammer mounted in said casing so as to be vertically movable against the bottom of the tape-holder for causing the explosions when the cane is driven downwardly against a hard object, a spring for normally holding said hammer away from the tape-holder, a trip for feeding the tape to the exploding position, and a connection between said trip and the hammer whereby they will move to gether.

In witness whereof, we have hereunto affixed our signatures in the presence of the witnesses herein named.
